My husband wont have sex with me.

So ever since he saw the baby move in our ultrasound he hasn't had sex with me. I finally said something and he said he doesnt want to because he saw her move in there. But it actually just make me feel unattractive now because I have a big belly and its bothering me so bad. And since I said to him that makes me feel unattractive he says I make it about me all the time. Which makes me feel more like shit. Anyone else having this problem?
